Hello,
I realized, that the Singleton Pattern seems not to be such a common one.
I tried the workaround with the Poolsize.
This is my jboss.xml:
| <?xml version="1.0"?>
| <jboss>
| <enterprise-beans>
| <session>
| <ejb-name>SessionLogCacheImpl</ejb-name>
| <configuration-name>Standard Singleton Stateless
SessionBean</configuration-name>
| </session>
| </enterprise-beans>
| <container-configurations>
| <container-configuration extends="Standard Stateless
SessionBean">
| <container-name>Standard Singleton Stateless
SessionBean</container-name>
| <container-pool-conf>
| <MaximumSize>1</MaximumSize>
| <strictMaximumSize>true</strictMaximumSize>
| </container-pool-conf>
| </container-configuration>
| </container-configurations>
| </jboss>
But this does not work properly.
I need this singleton for the reason that i want to store objects in a single
set from every Client. First I tried to use static sets. This worked out.
But i read that static should not be used in EJB.
Forther more this EJB has a timer. So when I have more than one EJB in the
pool, the Timer will be called more than once.
The only way i see to get this working is using singleton. But aint getting
this to work.
Has anyone any suggestion?
Thanks for your Help,
Alexander
